KAISER, or MILWAUKEE, WISCONSIN, AssIeNoE T KIECKHEEER coN- TAINER COMPANY, or MILWAUKEE, W1SCONSIN,"A COBPORATION or MAINE REENFORCED CONTAINER Application filed July 5, 1828. SetiaLNo. 290,655.,

This invention relates to improvements in reenforced containers.

It is one of the objects of this invention to provide a fibreboard container which has side portions reenforced by panels of a light weight but strong material such as plied wood.

It is a further object of this invention to provide a container in which the reenforcing 10 panels are attached to the sides in a very secure manner.

It is a further object of this invention to provide a container in which the reenforced side portions are provided with flaps which are scored deeply at the line of fold to receive the upper and lower edges of the reenforcing panels.

It is a further object of this invention to provide a container the parts of which fit 0 together and cooperate with one another in a novel manner to prevent weaving movement of the container when it is closed.

It is a further object of this invention to provide a reenforced container which is simple in construction, light in weight, strong and durable, and well adapted for the purpose described.

WVith the above and other objects in View, the invention consists of the improved reenforced container, and all its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawings, in which the same reference characters designate the same parts in all of the views:

Fig. 1 is a vertical sectional view taken through the container;

Fig. 2 is a sectional View on the line 22 of Fig. 1; and V V Fig. 3 is a plan view with the cover-flaps in the open position. i

Referringto the drawings, the container comprises a single sheet of fibreboard scored and cutto form end sections 5 and 6, and side sections 7 and 8. The section 5 is formed with flaps 9 and 10 which are toldable along deeply scored linesll and 12, respectively. The section 6 is formed with flaps 13 and 14:, which are foldable alongthe deeply scored lines 15 and 16, an'dis also formed with aside flap 17 which is secured tothe side section 7 by staples 18 or other securingjmeanaiwhen the container isassembled. The side section 7 is formed with upper and lower flaps 19 and 20, and theopposite section 8 is formed with similar flaps 21 and 22. The flaps 19, 20, 21, and 22 have their side'edges cut inwardly atan angle and then straight as at 19, 20, 21, and 22", respectively. 1 I, I I.

Secured to the'inner sides of the end members 5 and 6' are reenforcing panels 23' and 24, respectively, which are constructed preferably ofthree-ply wood. This type ofreenforcing'panel is very light in weight, but not withstanding this fact, possesses great strength. The panels are shown as secured to the end members by staples25, but it is obvious that other attaching means may be employed, suchas tacks, rope insertions, or glue. Instead of usingwply wood for the panels, heavy fiberboard may be employed.

To close the container, the flaps 9, 1.0, 13, and 1 1 are bent inwardly. The upper and lower edges ofthe reenforcing panels 23 and 24; arereceived by the grooves formed by the deeplyscored lines 11, 12, 15, and 16' as clearly shown in Fig. 1. This feature holds the panels securely in place and further braces the flaps, forming, a very rigid construction. In addition to this, the scored lines 11 and 15 project upwardly, and thelines 12 and. 16 project downwardly, forming ribs, so that the eontainerrests, on theselatter ribs and its weight is borne by the strong reenforcing panels.

Next the flaps19, 20, 21,3113 22 are bent inwardly, their inwardly cut edges 19, 20, 21,

and 22" fitting alongside of and within the ribs formed by the lines of scoring 11, 12, 15, and 16. Thus the edges of the flaps are braced against the ribs and lateral or weaving movement of the container is prevented.

This feature further presents a construction in which the outersurfaces of the flaps are flush with the outer surfaces of the ribs formed by thelines of scoring, so that the weight of the'container is borne by the reenforcing panels.

. The top andbottom of the container area are sealed by gluing or stapling, or by applying tape along the edges of the flaps.

Although the term fibreboard is employed in the specification and claims to describe the main body material, it is not desired to be limited to this particular material, as cardboard or any other semi-rigid material may be used without departing from the spirit of the invention.

From the foregoing description it may be seen that the improved reenforced container is simple in construction and well adapted for the purpose described.

What I claim is:

1. A container comprising a fibreboard body portion having side portions and reenforcing panels of rigid material secured to opposite side portions of said fibreboard body, said side portions having flaps foldable on lines of scoring, said lines of scoring being of a width greater than the thickness of the panels, and edges of the reenforcing panels eing received in the grooves of said lines of scoring when the flaps are bent inwardly.

2. A container comprising a fibreboard body portion having side and end portions and reenforcing panels of rigid material secured to the inner sides of said end portions, said side and end portions having flaps and having lines of scoring on which said flaps are foldable, said lines of scoring on the end portions forming inner grooves for receiving edges of the reenforcing panels and outer ribs, and said side flaps having edges cut in wardly to fit alongside of said ribs, the upper surfaces of said flaps being flush with the upper surfaces of the ribs.

3. A container comprising a fibreboard body portion, and reenforcing panels of rigid material secured to the inner sides of one opposite pair of side portions, said side portions aving flaps and having lines of scoring on which said flaps are foldable, said lines of scoring on the side portions having the reenforcing panels forming inner grooves for re ceiving the edges of the panels and also forming ribs, and the flaps on the other side portions having edges cut inwardly to fit alongside of said ribs, the upper surfaces of said flaps being flush with the upper surfaces of the ribs.

In testimony whereof, I afiix my signature.

WALTER R. KAISER.
